Heelless chunky heels

I'm working on a character design and I'm trying to find reference for a specific shoe so bare with me.
It's like a heelless heels, which exists, but the sole-bottom part extends further out back, like, below the heel part. I think it's for balance but whatever.
the closest I can find is bumper heels, but the one I'm thinking of comes out further.
Something close is that one heelless saint laurent that flopped, but I want it taller.
